Glenn Lord had erroneously
titled this story "The Valley of
the Lost," as he thought it was the story
that had been announced for the last issue of
STRANGE TALES that never got published; as
it turns out, he was wrong, and when the proper story
showed up, Glenn Lord titled it "The Secret of
Lost Valley."

Since this initial mistake, everyone
has gone back to the proper titles.
A titled
version is included in a list of REH stories
that Otis Adelbert Kline
possessed, titled "King of the Forgotten
People."
Otis Adelbert
Kline and later agents retained the
original typescript and it was eventually donated
to Cross Plains Library.
